How to Make DIY Easy Homopolar Motar in Just 3 Steps

In this instrutables we're going to make a homopolar motar which is very easy to build and fun.

its a great way to teach science to young ones and to give them knowledge about the different aspects of science like magnetism & electronics.

How it works ?

Well, its works on the principle of Lorentz Force. As it moves through a magnetic field, the conductor is pushed through a magnetic field by opposing forces. This force induces a torque around the axis of rotation. Because the axis of rotation is parallel to the magnetic field, and the opposing magnetic fields do not change polarity, no commutation is required for the conductor to keep turning.

What we need -

1. A non insulated copper wire https://www.amazon.com/Valuepro-Non-Insulated-Anne...
2. Neodymium Magnets https://www.amazon.com/Valuepro-Non-Insulated-Anne...
3. Batteries https://www.amazon.com/Duracell-CopperTop-Alkaline...

Bend the wire in any shape as you like but just remember the weight of the copper wire is well distributed.

I prefer to start with the spiral shape as its my favorite and easy to make also.

Take a marker with lager diameter ( slightly larger than the battery) and Wrap the copper wire around the marker a few times for a nice spiral look.

CAUTION - Please be careful while using Magnets they have very strong force So look out that no skin gets in between.

For more clearness look at the above images.

Now take magnets and mount the magnets to the negative pole of the battery.

Now bend the other end of the copper wire so that it touches the magnets and completes the circuit.

You will feel some force of the wire after that :)

Our homopolar motar is ready to spin place the battery with the magnet down on a level surface and put the copper wire on it. you can try different shapes, It is important that the copper wire is well balanced, if this is not the case, it will run off the positive pole and stop working.

Now you can learn as well as play and that is science all about.

I hope you enjoyed

Thanks for watching :D
